BUYING ADVICE! '08 w/ only 4hrs...

Thanks in advance guys!



Michigan trail rider. Might do a couple of practice days this year.


I'm looking at an '08 YZ450F that has only 4 hours on it. I spoke briefly with the seller who is also the original owner he's embarrassed that he only wrote it four times and estimates at an hour each. 


It was obvious to me that he had little knowledge of bikes in general and he admitted that it took him some time to figure out how to start it so I think it's safe to assume little to no maintenance has been done. I failed to ask about oil/air changes but will do so tomorrow.



- Is there anything to be concerned with on a bike having sat like this? Things to look for?

- Besides the obvious, oil/air filter/clean carb, what else might you guys do to help ensure that this is a long-haul bike?


 I will get into mods at a later point, but first just want to be sure to do all that I can to help this purchase last, should I make it.

A great MX bike but a terrible choise for trail riding...It's geometry is set for high speed stability and sweeping MX turns and berms. It's a fat pig in the tight MI trails.

What type of rider are you and what type of trails are you riding? For an experienced rider with an MX background this could be a great trail bike for open fast trails. All tight stuff...a 250 two stroke might be a better option. For a less experienced rider this could be a handful.

If it only has 4 hours it should be fine. These mx motors are tough and designed to be ridden hard. When buying a 4 stroke you want low hours IMO. I bought my 11 and it was also barely used. If he did not change the oil that's not a big deal. Just change it when you get it. I trail ride with a guy who has an 09 and it runs great. He has a rekluse on it.

Thanks Guys...

A couple of the specif approach:

- What if a proper break-in procedure was not followed?

- From photos I see plenty of surface rust/corrosion in areas like chain, sprockets, pads, rotors, header guard, rims, bolts, etc... Again, obvious signs of no attention and long term storage, can this be an indication of the internal condition as well or have I found a gem "for the right price"?

Does it run? Let's just start there.

If the engine runs you will usually hear any problems and see if you can run it through the gears.  A little corrosion is OK...a lot may show the sings of abuse.  Again these motors are tough as nails.  Prolonged sitting can affect seals.

Adding to the great input already, yes, make sure it starts. Does it start cold? Does it start hot (after letting it warm up and maybe doing a quick spin).

I loved the 08. Felt like a big-bore 250F.

If the bike has sat that long, you have to ask yourself whether you can go through the carb by yourself.  It's very likely that the pilot jet will have been partially clogged by dried fuel, and if so, it will run like crap, if it starts.  In that situation, you'd need to be able to identify the problem as being the carb, or something else. 


Also, depending on the environment it's been stored in and a number of other factors, there is a small chance of internal corrosion conditions having developed in the engine.

      2005 YZ450F, Athena Big Bore, Power Bomb, Q4.
      Ok.  Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits.  Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it.  3 weeks ago, went out to the track, and after about 20 laps, it started leaking again.  Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low.  Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft.  Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
      So, what the heck am I missing?  I'm totally stumped on this one.  Is something wrong with my case cover?  Do I need to replace the w/p itself?  I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt.  Any help or suggestions is greatly appreciated.  Thanks!

      Alright guys, my 04 YZ450f runs fine minus some slight backfires when decelerating (need to adjust fuel screw). The other day when I was done checking my valve clearances I changed the oil and filter and put the bike back on the stand, kicked it a few times without the ignition coil in to get some oil flowing got off and noticed a little drip spot on the ground, it was no bigger than a dime so I thought nothing of it. Started the bike with no issues took it for a quick 10-15 min ride, came back to the garage to find out my whole case was soaked with oil and it started pooling in the low spots on the clutch basket side. I cleaned all the oil off and took it out again for 5 mins to try and see where it was coming from, here are my three possible places but nothing directly leads me to believe it’s any of the three either.
      1. Decompression plug area
      2.  Valve cover gasket leak (not really sure because the amount of oil leaking Looks to be a large amount
      3. Oil tank (bad weld or cracked weld somewhere
      what are you guys thinking?

      Hey guys. I could really use your help diagnosing an issue that came up riding today. Bike is a 2013 YZ450F. Well maintained and haven't had any issues until now. Both the oil and coolant are new and levels are to spec. 
      After riding for about an hour in the sand dunes, I noticed a grinding going on on the right side of the bottom end (from what I could tell). When I looked to see what was going on my kickstarter was vibrating and grinding really loud. This was a different sound than if you engaged the kickstarter while running. It sounded less "clanky" and more "vibrating/grinding" if that makes sense. Grabbing the kickstarter and moving it didn't help the issue.
      When I noticed it, I shut the bike off and gave it a second. Being a few miles deep into the dunes, I had to get it out of there so I started it back up and it seemed fine- no grinding. I headed back to the car and after a few minutes, it came back so I shut it off again, started it back up and nothing. That process happened one or two more times before I made it back to the truck. Seemed to run fine otherwise. 
      Once I got it back to the truck I started it up and tried to pay more attention to what was going on but it wasn't doing it. I did seem to have more of a metal on metal noise coming from the motor. I started and stopped the bike a few times and after the motor stopped there was a distinct metal clank/grinding noise that happened right after the motor shut of for maybe half a second. This doesn't happen every time. 
      I tried doing some research and have seen things that make me think it could be the spring that connects to the kickstarter, or the kickstarter stopper plate- but really I have no idea.
      Seems strange that the issue is off and on.
      Thanks for the help!

      Does anyone know if there is any differences between the 2 radiators? Will the yz450fx radiator bolt on a yz450f? What I am wanting to do is wire up a fan to my 2016 yz450f. I know how I am going to do it I just don’t want to use a “universal” fan kit. What I would like to do is get a 450fx radiator and the direct bolt on Trail Tech fan for that radiator to have a good clean look.
